ABSTRACT:
Rotary actuator for a divided stabilizer on a motor vehicle axle, comprising a cylinder which is closed on the ends by two caps and forms a work chamber, ribs which run axially on the inside diameter of the cylinder, a motor shaft with splines which have the same axial length as the ribs of the cylinder, whereby the splines of the motor shaft and the ribs of the cylinder divide the work chamber into individual work chambers, a first and a second hydraulic connection for two separate work chambers, a connection system between the work chambers which hydraulically connects the work chambers at least in pairs, whereby the connected work chambers are arranged so that the work chambers corresponding to the first hydraulic connection alternate with those which are connected to the second hydraulic connection, and connection surfaces on the cylinder and on the motor shaft for the stabilizer parts, whereby the motor shaft has a blind hole with a profile to locate one of the stabilizer parts.
